Product Name: SWT-3.6-107 Wind Turbine

Product Description

The SWT-3.6-107 wind turbine is the latest model in the product range. It is suitable for offshore applications and for onshore wind farms. Rotor The rotor of the SWT-3.6-107 turbine is a three blade cantilevered construction, mounted upwind of the tower. The power output is controlled by pitch regulation. The rotor speed is variable in order to maximize the aerodynamic efficiency and the speed compliance during power regulation minimizes the dynamic loads on the transmission system. Blades The blades are made of fiberglass reinforced epoxy and are manufactured by Siemens in a single operation, using our patented IntegralBlade® process. No glue joints between spars and shells, no weak points, no easy access for water or lightning. The aerodynamic design of the blades represents state-of-the-art wind turbine technology, and the blades have been thoroughly tested at Siemens' test site under both static and dynamic loadings. The blades are mounted on pitch bearings and can be feathered 90 degrees for shutdown purposes. Each blade has its own independent fail-safe pitching mechanism capable of feathering the blade under any operating condition, and allowing fine-tuning to maximize power output. Gearbox and brake The gearbox is a custom-built 3-stage planetary - helical design, mounted on the nacelle with flexible rubber bushings, thereby providing a compact high-performance construction and the lowest possible noise level. The gearbox is fitted with a fail-safe mechanical brake at the high-speed shaft. Generator The generator rotor construction and stator windings are specially designed for high efficiency at partial loads. The generator is fitted with a separate thermostat-controlled ventilation arrangement, and by ensuring a very efficient cooling the generator can be operated at temperatures well below the normal level of the standard insulation class, thereby providing the best possible lifetime of the winding insulation. Tower The SWT-3.6-107 turbine is mounted on a tapered tubular steel tower. The tower has internal ascent and direct access to the yaw system and nacelle. Controller The turbine controller is a microprocessor-based industrial controller; similar to the type used in other Siemens wind turbines. The controller is complete with switchgear and protection devices. It is self-diagnosing and has a keyboard and display for easy readout of status and for adjustment of settings. Operation The wind turbine operates automatically, self-starting when the wind reaches an average speed of about 3–5 m/s. The output increases approximately linearly with the wind speed until the wind reaches 13–14 m/s. At that point the power is regulated at rated power. If the average wind speed exceeds the maximum operational limit of 25 m/s the turbine is shut down by feathering of the blades. When the wind drops back below the restart speed the safety systems reset automatically. Safety system The turbine has several redundant levels in the safety system, including an independent pitch system for each of the blades, and as a result the turbine can shut down safely from any operational condition. Remote Control The turbine is equipped with the unique WebWPS SCADA system. The system offers long-distance control and a variety of status views and useful reports from a standard internet web browser. Grid compliance The SWT-3.6-107 turbine is fitted with our proprietary NetConverter® system that is compliant with even very demanding grid codes. The NetConverter® system has ride-through capability for all normal faults.
